Hey guys I have a few questions for you. I am not that good with computers and have a couple year old HP Pavilion a1630n. I would like to update the graphics card but I am not sure what is best for me. The current one is the one that came with it, NVIDIA GeForce 6150 LE. What is best for this computer and what is even compatible? I am looking for $100-$250 Price range, thanks!
Also will DL'ing games to my PC slow down its other processes?
Your HP is a Athlon X2 at 2.4 ghz, I believe.
You also have a 16x PCIe slot.
I am going to say that something along the lines of a 9600GT, maybe even a 4850 if you have enough power to run it.
What kind of resolution is your monitor? Check on your Power Supply and see what the wattage is, THAT will be your biggest limiting factor.
